What Is a Brass Sealing Screw?
A brass sealing screw is a small, precision-turned fastener made from brass. It closes and secures an enclosure, and it is usually built in one of two ways.
- Tamper-evident type: a cross-drilled hole in the head or shank lets a wire and lead seal pass through. If anyone opens the enclosure, the broken seal shows it. This type is common in electricity meters, panels and utility boxes.
- Leak-proof type: a screw with a sealing face, gasket or O-ring groove that blocks liquids, gas or dust.
At OK Engineers, we make both types to your specification.
Why Buyers Choose OK Engineers as Their Brass Sealing Screw Manufacturer
Buyers rarely complain about the price of a small screw. They complain when a batch arrives with loose threads, uneven plating or a hole in the wrong place. Enough of those and a whole assembly line stops.
That is why we run our process around consistency.
- Made in Jamnagar, India’s brass hub. Our factory sits in a cluster where brass raw material, skilled turners and tooling suppliers are all close by.
- Generations of brass experience. OK Engineers (also known as Om Kailash Engineers) is a family-run business. Our team has spent years learning which alloys machine cleanly and which tolerances actually matter.
- ISO 9001:2015 aligned quality systems. You can trace each batch from raw rod to final packing.
- Custom first. We make to your drawing, sample or standard (metric, BSW, UNC or BA threads).
- Export ready. We handle commercial invoices, packing lists, certificates of origin and material test certificates for every shipment.
Our Range of Brass Sealing Screws
We do not sell one screw in one size. Here is what we regularly produce.
Brass Meter Sealing Screws
These are used in single-phase and three-phase energy meters and electronic meters. A precisely placed cross-hole holds the seal wire. Utilities and meter OEMs use them to protect against tampering.
Brass Panel and Enclosure Sealing Screws
These go on distribution boards, switchgear covers, terminal covers and junction boxes. Head styles include hex, slotted, pan, cheese and custom security profiles.
Brass Sealing Screws with Gasket or O-Ring Groove
We machine sealing faces and grooves for applications that must stay leak-proof, such as plumbing, fluid systems and sensor housings.
Custom Brass Sealing Bolts and Special Screws
If your design needs an unusual head, shoulder length or thread combination, send us the drawing. Most custom jobs go from drawing review to sample in a short turnaround.
Technical Specifications
The table below shows what we typically offer. If your requirement falls outside it, ask. Most non-standard requests are possible.
Parameter | Typical Offering |
Material | Free-cutting brass (CW614N / CuZn39Pb3, C36000 equivalent), other brass grades on request |
Thread standards | ISO metric, BSW, UNC/UNF, BA, custom |
Size range | Approx. M2 to M12 (larger on request) |
Head styles | Hex, slotted, pan, cheese, round, custom |
Seal hole | Cross-drilled through head or shank, size per drawing |
Surface finish | Natural brass, nickel plating, tin plating, zinc plating, custom |
Tolerance | As tight as ±0.02 mm on critical dimensions, depending on design |
Manufacturing | CNC turning, threading, drilling, deburring |
Inspection | Dimension check, go/no-go thread gauging, plating and visual inspection |
Documents | Material test certificate, RoHS/REACH declaration, certificate of origin |
Note: Ask us for a drawing review before you finalize tolerances. A small design change can cut your unit cost without affecting performance.
Why Brass Is the Right Material for Sealing Screws
Brass is an alloy of copper and zinc. For a sealing screw, several of its properties matter at once.
- Corrosion resistance. Brass handles humidity, moisture and most indoor and outdoor conditions better than plain steel.
- Excellent machinability. Free-cutting brass produces crisp threads and clean cross-holes, which is why it is the standard for precision-turned parts. The Copper Development Association publishes good technical background on copper alloys.
- Electrical conductivity. This helps when the screw also serves as an earthing or contact point.
- Non-sparking and non-magnetic. This is useful in sensitive electrical and instrumentation environments.
- Easy plating. Nickel or tin plating adds a clean finish and extra wear resistance.
Brass vs Other Materials
Feature | Brass | Stainless Steel | Mild Steel (Plated) | Aluminum |
Corrosion resistance | Very good | Excellent | Fair (depends on plating) | Good |
Machinability | Excellent | Moderate | Good | Very good |
Electrical conductivity | Good | Low | Low | Good |
Strength | Moderate | High | High | Lower |
Tamper-seal suitability | Excellent (clean cross-holes) | Good (harder to drill) | Good | Fair (softer) |
Cost per piece | Moderate | Higher | Lower | Lower |
Best for | Meters, panels, electrical, plumbing | Harsh, high-strength uses | Low-cost general use | Lightweight housings |
The takeaway: brass gives the best all-round balance for sealing screws in electrical and fluid applications.
Where Brass Sealing Screws Are Used
Our screws end up in more places than most buyers expect.
- Energy meters: single-phase, three-phase and smart meters
- Electrical panels and switchgear: covers, terminal blocks and MCB enclosures
- Utility and gas meter housings
- Plumbing and water fittings
- Automotive and industrial equipment
- Telecom and instrumentation boxes
- HVAC and control systems
If you do not see your industry here, send your drawing anyway. Brass screws suit many uses beyond this list.
How We Make Every Brass Sealing Screw
A good screw comes from a controlled process, not a lucky batch. Here is how we do it.
- Drawing review. Our engineers check dimensions, thread class and seal-hole position, and flag anything that could cause trouble in production.
- Raw material selection. We use brass rod from approved sources and check it against the alloy you asked for.
- CNC turning and threading. Single-spindle CNC machines cut the head, shank and thread in one controlled setup.
- Cross-drilling and deburring. The seal hole is drilled to your specified size and position, then cleaned so it will not cut the seal wire.
- Surface finishing. Natural, nickel, tin or any other finish you specify.
- Quality inspection. We check dimensions, gauge the threads and inspect the finish before packing.
- Export packing. Screws are packed to prevent scratching and moisture damage in transit, and labelled by batch.
Quality Control and Compliance
Sealing screws are safety-relevant parts. A poor batch can lead to a failed inspection, a rejected meter lot or a field complaint. Here is how we reduce that risk.
- Go/no-go thread gauging on sampled lots
- Dimensional checks against your drawing
- Plating and visual inspection for finish consistency
- Batch traceability so we can find the source of any issue quickly
- Compliance support forRoHS andREACH declarations, which most European buyers require
Our systems follow the principles ofISO 9001:2015. Free-cutting brass generally contains some lead and falls under a RoHS exemption for copper alloys. If your product touches drinking water or needs lead-free material, tell us early so we can discuss suitable alloys.
Custom Manufacturing: From Drawing to Delivery
Many of our best customers started with a sample and a question: “Can you match this?”
Yes, and often improve on it. You can send us any of the following.
- A 2D or 3D drawing (PDF, DWG, STEP)
- A physical sample
- A standard reference (thread type, head style, finish)
- A description of the application, so we can suggest the right design
We will confirm feasibility, suggest changes if they save cost, and send a quote and pre-production sample if needed.

Tips for Buyers: How to Choose a Brass Sealing Screw Supplier
Whichever supplier you use, ask these questions first.
- Do they manufacture in-house? Middlemen add cost and cut your visibility on quality.
- Can they show inspection records? Ask what they check and how often.
- Do they understand your standard? Metric, BSW and UNC are not interchangeable.
- Will they sample first? A supplier confident in their work is happy to prove it.
- Are export documents handled properly? Missing paperwork can hold a shipment at port.
- How do they handle problems? Ask how a rejected lot is replaced or credited.
